Description
Technical field
The present invention relates to water resource and environmental technology field, more particularly, relate to water body of different nature in the spacer ocean, it is mixed that itself and peripheral water body are not oozed mutually, the isolation and the memory method of heterogenous water in promptly a kind of water body in large.
Background technology
Tellurian gross amount of water resources, fresh water only account for 2.5%, and seawater accounts for 97.5%, and along with increase, the expanding economy of population, shortage of fresh water has become a worldwide problem.Estimate that according to the United Nations and the World Bank people's in the whole world 2/3 in 2025 water will be difficult to guarantee.The freshwater resources situation of China also allows of no optimist: at present, about normal nearly 400 billion cubic meters of time water deficit, wherein irrigate about about 300 billion cubic meters of lack of water.In more than 660 city, the whole nation, more than 400 urban water shortage arranged, wherein 108 is the city of severe water shortage.Shortage of fresh water and even water crisis are one of maximum 'bottleneck' restrictions in China's sustainable development of socio-economy process (National Development and Reform Committees 2005).And the densest area of population is the area, coastal delta in downstream, river course, and this also is fresh water area the most in short supply, and China coastal cities almost are the lack of water city entirely.Therefore, wanting water, want resource to the sea, is that the reality that solves coastal (coastal waters) regional shortage of fresh water is selected, and also is to realize with sustainable utilization of water resource, ensure the vital measure of coastal, coastal waters, island regional economy social sustainable development, be of great immediate significance and strategic importance.
Have 10,000 6 hundred billion cubic metres fresh water to run off into the sea on the coastline that China is 10,000 8 thousand kilometers, for coastal, coastal waters and island, this is a huge and valuable wealth.The exploitation of this being gone into sea water and fresh water has two technology paths to walk, and the first is let go earlier and allowed seawater pollution fresh water, and then desalination by every means, and the technology path that desalinization is just walked promptly pollutes earlier the technology path of afterwards administering; Other method is before light, the mutual blending of salt water, manually isolates light, salt water, realizes storing the target of fresh water Yu Haiyang.
In addition, aspect the marine eco-environment,, very big to halobiontic destruction as one of marine organisms four big killers' ship ballast water.How to make the boats and ships discharged ballast water can reach the not target of polluted seawater, make each research institution of the whole world actively develop the research of purification technics.Present technology path almost completely concentrates on the qualified discharge.
Moreover, the current turbidity is bigger near the sea outfall, need under the peace and quiet seawater situation at some, how can fastly build clarification and preserve clear water? the water body that how to guarantee different in kind coexists in the ocean and unlikely blending, pollutes mutually, also be: seawater do not pollute fresh water, water ballast not polluted seawater, muddy water do not pollute clear water, be the technical barrier that exists now.
Summary of the invention
Technical problem to be solved by this invention is: overcomes the deficiencies in the prior art, the isolation and the memory method of heterogenous water in a kind of water body in large is provided, i.e. and water body of different nature in the spacer ocean, it is mixed that itself and peripheral water body are not oozed mutually; In other words the present invention's target that will reach is: store fresh water, clear water or water ballast in seawater (in other words at salt water), and the water body of being stored is not polluted by local seawater.
The isolation of heterogenous water and memory method in the water body in large of the present invention, be achieved by following technical proposals, in water body in large, utilize the ocean reservoir to isolate or the storage heterogenous water, described ocean reservoir is in the hard water proof body soft body dam to be set, store heterogenous water (being fresh water, water ballast or clear water) in the soft body dam, described soft body dam is by waterproof fexible film, buoyancy aid and heavily weigh down and forms, and described waterproof fexible film hangs under the buoyancy aid, and directly is depressed into sea bed by heavy bob.
Between soft body dam of the present invention and the hard water proof body is the water quality intermediate zone, and the water quality intermediate zone contains local seawater or landlocked intermittent sewage of coming.
Hard water proof body of the present invention can be constituted or is made of marine hedge by large-scale sandbag.
Soft body dam of the present invention can be that body is fixed in the bottom by anchor chain; Described soft body dam two ends and limit bank constitute a sealing ring, or two ends are connected and constitute a sealing ring.
In the hard water proof body of the present invention at least one soft body dam is set; Described soft body dam has one deck water-separating film at least.
The invention has the advantages that: the operating principle of traditional reservoir is fixing water surface area, is that the variation of the depth of water realizes regulating and storing of heterogenous water by vertical direction; Operating principle of the present invention then is the fixing depth of water, and that the variation by the area of plane realizes is rich, the regulating and storing of low water.Because last method will bear pressure differential, so want resistance to compression, want antiseepage, so cost is big.And soft body dam does not have huge pressure differential, does not have the antiseepage requirement, so cost is low, flexibility is big.
The ocean reservoir is located among the seawater, will be introduced into and be stored in the reservoir with the water body of local seawater different in kind.This reservoir comprises two-layer promptly hard, soft two-layer water proof body; hard water proof body plays the protection soft body dam; be equivalent to a hard shell, the water body of local seawater different in kind (as high-quality fresh water) is stored among the long curtain of film of soft body dam, is equivalent to a telescopic inner bag.Because the existence of hardware water proof body has reduced the influence that marine motor can produce soft body dam; Owing to the existence of the long curtain of soft body dam film, reduce the cost of hard water proof body equally, made the ocean reservoir have anti-salt, storm guard tide, the multiple function of bilge water resisting.
Soft body dam is made of the long curtain of a kind of special film, the long curtain of the curling film that closes up of particular design is dropped in the marine site that hardware water proof body surrounded, under heterogeneous effect of water pressure endlessly, the expansion of will constantly outwards expanding of the long curtain of film, the retaining volume increases, the also corresponding increase of water retention capacity.On the contrary, if draw water from curtain, the heterogeneous water yield reduces, and then heterogenous water pressure also reduces, and the long curtain of film will dwindle automatically, and making it remain with the long curtain of film glassware for drinking water outward has the pressure that is equal to, thereby reaches the purpose that stores the heterogenous water Yu Haiyang.
The hard water proof body of ocean reservoir has the attack that subtracts the anti-effect of floating of stream, can resist local wave, and the water body zone of a relatively placidity is provided for reservoir.Soft body dam then comprises the buoyancy aid of bubbling through the water column, and is suspended from the film under the buoyancy aid, and falling body combined with sea bed under film dependence deadweight reached, and divided thin film is every the heterogeneity water body.Buoyancy aid, flexible film and weight three and water front are formed the ring of encirclement of a sealing, and can carry out automatic adjustment on the area of plane according to the water yield in the ring of encirclement.
Soft body dam can be separated water body of different nature, as become, fresh water, clear, muddy water and water ballast etc.Between soft body dam and hard water proof body is the water quality intermediate zone.
For the fresh water reservoir, fresh water by the effluent mouth import, also can be through the island, river mouth or the two sides water channel directly import, dry point generally is positioned at the upstream, river mouth, the more excellent place of water quality.Also can heterogenous water be imported reservoir through pumping plant and pipeline.Inshore a plurality of oceans reservoir can pass through channel or pipeline UNICOM, to realize distruting water transregionally.In the reservoir of same ocean, a plurality of soft body dams can be set, to increase safety factor.Viewable design requires to add sluice gate on hard water proof body, with water level in the balancing reservoir.
